INVENIOR JOHN RAYMOND SMITH ATTORNEY United States Patent Ofii ce3,011,207 Patented Dec. 5, 1961 3,011,207 VACUUM DANDRUFF HAIR" BRUSHJohn Raymond Smith, Box 481, Rockingham, N.C'. Filed Nov. 24, 1958, Ser.No. 775,976

1 Claim. (Cl. 15344) The present invention relates to a hair brush andmore particularly to a suction type hair brush for removing loose hairand dandruff during the hair brushing operation. Although the vacuumtype hair brushes have previously been provided they have not beenentirely satisfactory in that ,much of the loose hair and dandruff werenot effectively collected and the structure was not easily cleaned. 1

An object of the present invention is to provide a vacuum type hairbrush which serves to remove loose hair and dandruff during the brushingoperation and which overcome some of the problems of prior art devices.

An object of the present invention is to provide a suction type hairbrush which can be readily cleaned and which can be easily dis-assembledfor cleaning and readily assembled for use. v

A further object is to provide a filter element which can be readilyremoved and either thrown away or cleaned and returned to operativeposition.

Other and further objectives will be apparent as the descriptionproceeds and upon reference to the accompanying drawings wherein:

FIG. 1 is a horizontal section view through the body of the assembledbrush and showing the suction passage way from the bristle area to thefi'lter and the vacuum and fan chamber from the filter and showing themotor in plan and alsofshowing the connectionof the motor to the brushhead;

FIG. 2 is a section on line 22 of FIG. 1 showing the brush with themotor disassembled and some of the bristles omitted showing the passagesfor air with arrows indicating the direction of movement of the air;

FIG. 3 is an elevation of the filter element and the cooperating cap forretaining the filter in position.

Upon more detailed reference to the drawings, the hair brush comprises abrush head body of suitable material with bristles 11 extending from oneside thereof and around the periphery of the brush head to provide achamber within the peripheral bristles. Such chamber within the bristlescommunicates by means of a suction passageway system having a pluralityof small passageway portions 12 communicating from the chamber withinthe bristles to diagonal passageways 13 which communicate with alongitudinal passageway 14 to a transverse filter receiving bore 15.Said passageways 12, 13 and 14 provide a suction passageway system fromthe bristle area to the transverse. substantial cylindrical bore 15. Ahollow cylindrical filter element 16 provided with a conical tip 17 isreceived in transverse bore with the tip 17 in a conical recess 18 inthe end of the transverse bore 15. The filter element 16 is providedwith positioning lugs 18A which cooperate with slots 19 to position thefilter element in proper operative position. The filter element includesspaced perforated sections 20 with a central section 21 therebetween thecentral section being provided with an inlet aperture 22 which registerswith a circumferential groove 23 communicating with suction passageway14 for carrying hair and dandruff by the stream of air into the filterelement 16.

The filter is held in correct position by means of a cap 24 having malethreads threaded into female threads in the brush body 10.

way includes .an internally threaded female coupling portion 26 whichreceives a threaded male nipple 27 on the handle which carries anelectric motor 28. Motor 28 has shaft extension'29 which carries a fan30 with a fan being of a size to be received within the vacuumpassageway 25. It will be noted that the nipple 27 is hollow andisprovided with outlet means 31 for the passage of filtered air'ffrom thevacuum passage 25.

It will be apparent that the parts may be readily assembled anddisassembled and that the structure provides a relatively large fanreceiving chamber in the female coupling member 26 whereby the structureis effective for the purpose described.

'It will be noted that air passing from the suction passageway must maketwo substantially right angle turns which assists in the removal of thedandruff and hair from the stream of air while the small apertures 20Ain the apertured sections 20 additionally assure effective-- lyfiltering the remaining dandruff and hair from the air passingtherethrough.

What I claim is: g A hair brush comprising a brush head having bristlesalong the periphery thereof, said brush head being provided with asuction passageway extending from aperture means surrounded by thebristles of the brush head and extending toward one end of the brushhead, said brush head being provided with a transverse substantiallycylindrical bore communicating with said suction passageway from thebristle area, said brush head being provided with a vacuum passagewayextending from said transverse bore and separated from said suctionpassageway from the bristles by said transverse bore, a hollowcylindrical filter element removably mounted in said transverse bore andhaving a peripheral inlet opening in communication with the suctionpassageway from said bristles, and having small holes for filtering theloose hair and dandruff and retaining such loose hair and dandruff inthe cylindrical filter element, said vacuum passageway in said brushhead extending from areas surrounding the portions of the filter elementprovided with the small apertures and terminating in a female couplingelement, to provide a large fan receiving chamber, a handle for saidbrush, a motor in said handle and having a. shaft projecting asufiicient distance to extend into the fan'receiving chamber ofsaidbrush head, a fan on said shaft, said handle including a nippleportion detachably received in the female coupling portion of said brushhead whereby the fan may be readily inserted into the fan receivingchamber, outlet air exhaust means disposed on the handle side of saidfan, and means to positively detachably secure said nipple in saidfemale coupling, and means to provide registration of the inlet openingto said filter element and the said suction passageway from saidbristles, and removable means to close the transverse bore and retainthe filter element therein and to provide for removal of the filterelement.
